OcrInput.DeepCleanBackgroundNoise() - Heavy background noise removal.This is very useful for OCR because Tesseract tolerance for skewed scans can be as low as 5 degrees. OcrInput.Deskew() - Rotates an image so it is the right way up and orthogonal.Erosion removes pixels on object boundariesOpposite of Dilate OcrInput.Erode() - Advanced Morphology.Dilation adds pixels to the boundaries of objects in an image. OcrInput.Dilate() - Advanced Morphology.White becomes black : black becomes white. OcrInput.Invert() - Inverts every color.This filter should only be used where noise is expected. OcrInput.DeNoise() - Removes digital noise.This filter often improves OCR speed and accuracy in low contrast scans. OcrInput.Contrast() - Increases contrast automatically.Unlikely to improve OCR accuracy but may improve speed OcrInput.ToGrayScale() - This image filter turns every pixel into a shade of grayscale.May Improve OCR performance cases of very low contrast of text to background. OcrInput.Binarize() - This image filter turns every pixel black or white with no middle ground.For anti-clockwise, use negative numbers. OcrInput.Rotate( double degrees) - Rotates images by a number of degrees clockwise.Input filters to enhance OCR performance which are built into IronOCR include: OneLiner string Text = new code to clipboard VB C# List of OCR Image Filters The code sample below shows how easy it is to read text from an image using C# or VB. OCR with Tesseract 5 - Start Coding in C# NET Tesseract APIs and web services do not perform so well on these real world use cases. Iron OCR shines when working with real world images and imperfect documents such as photographs, or scans of low resolution which may have digital noise or imperfections. Can be used to redistribute Tesseract OCR inside commercial & proprietary applications.Extract Images, Coordinates, Statistics and Fonts.125 international languages all managed via Nuget or OcrData files.Deploy on Windows, Mac, Linux, Azure, Docker, Lambda, AWS.To perform OCR an almost any Image file or PDF.MVC, WebApp, Desktop, Console & Server Application compatible.Accuracy 99.8% significantly outperforms regular Tesseract.Includes for Tesseract 5, 4 and 3 Engines out of the box.Why C# developers choose IronOCR over Vanilla Tesseract:
#Linux ocr pdf to text software#
NET software library.Ĭhoose IronOCR to achieve 99.8%+ OCR accuracy without using any external web services, ongoing fees or sending confidential documents over the internet. Iron OCR is an easy-to-install, complete and well-documented.
#Linux ocr pdf to text install#
The first thing we have to do is install our OCR library into a Visual Studio project. NET OCR library using the most advanced Tesseract engine known, anywhere. NET platform software developers to recognize and read text from images and PDF documents. IronOCR is a C# software library allowing. Visual C++ Redistributable for Visual Studio.Save image with different image processing applied.X and Y coordinates change in OcrResult Class.Reduce file size of output PDF in IronOcr.
